Abstract: At least a part of a positive electrode lead (110) and at least a part of a negative electrode lead (120) are bonded to each other. A plurality of the positive electrode leads (110) and a plurality of the negative electrode leads (120) are folded back from one of a plurality of first battery cells (100a) and a plurality of second battery cells (100b) to the other of the plurality of first battery cells (100a) and the plurality of second battery cells (100b) through the at least a part of the plurality of positive electrode leads (110) and the at least a part of the plurality of negative electrode leads (120).

Abstract: A conveyor is provided with a supply roll, a detection device and a brake force applying device. The supply roll is rotatably arranged and is configured to support a belt-shaped cell material for an electrode or a separator to intermittently feeding out the cell material by rotation of the supply roll. The detection device is arranged with respect to the supply roll to detect an amount of the cell material remaining on the supply roll. The brake force applying device operatively coupled to the supply roll to apply brake force to the rotation of the supply roll based on the amount of the cell material detected by the detection device.

Abstract: A conveyor is provided with a conveyor section, a controller, a confirming part and a detecting part. The conveyor section conveys a belt-shaped work having a plurality of reference points arrayed discontinuously on a surface. The controller selectively operates the conveyor section for intermittently conveying the work for each prescribed interval as a first conveying mode and continuously conveying the work as a second conveying mode. The controller further operates continues the first conveying mode when the reference points are confirmed by a confirming part during the first conveying mode and switching to the second conveying mode when the reference points are not confirmed by the confirming part. The controller further continues the second conveying mode until the reference points are detected by the detecting part during the second conveying mode and switching to the first conveying mode when the reference points are detected by the detecting part.
